* Privileged containers can now restart if the host devices changeJake Correnti2022-06-06
| | | | | | | | | | | | | | | | | | | | | | If a privileged container is running, stops, and the devices on the host change, such as a USB device is unplugged, then a container would no longer start. Previously, the devices from the host were only being added to the container once: when the container was created. Now, this happens every time the container starts. I did this by adding a boolean to the container config that indicates whether to mount all of the devices or not, which can be set via an option. During spec generation, if the `MountAllDevices` option is set in the container config, all host devices are added to the container. Additionally, a couple of functions from `pkg/specgen/generate/config_linux.go` were moved into `pkg/util/utils_linux.go` as they were needed in multiple packages.

* linter: enable unconvert linterValentin Rothberg2022-05-19

* Switch all calls to filepath.Walk to filepath.WalkDirDaniel J Walsh2022-03-27
| | | | | | | | | WalkDir should be faster the Walk, since we often do not need to stat files. [NO NEW TESTS NEEDED] Existing tests should find errors. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* rootless: drop permission check for devicesGiuseppe Scrivano2022-01-27
| | | | | | | | | | | | | commit 350ede1eeb6ab33bce2918d7768b940c255e63c6 added the feature. Do not check whether the device is usable by the rootless user before adding to the container. Closes: https://github.com/containers/podman/issues/12704 [NO NEW TESTS NEEDED] it requires changes on the host to test it Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

* Pod Device Supportcdoern2021-09-20
| | | | | | | | | | added support for pod devices. The device gets added to the infra container and recreated in all containers that join the pod. This required a new container config item to keep track of the original device passed in by the user before the path was parsed into the container device. Signed-off-by: cdoern <cdoern@redhat.com>
* Add filepath glob support to --security-opt unmaskDaniel J Walsh2021-05-04
| | | | | | | | Want to allow users to specify --security-opt unmask=/proc/*. This allows us to run podman within podman more securely, then specifing umask=all, also gives the user more flexibilty. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* Enable more golangci-lint lintersPaul Holzinger2021-02-12
| | | | | | | | | | | | | | | | | Cleanup the golangci.yml file and enable more linters. `pkg/spec` and `iopodman.io` is history. The vendor directory is excluded by default. The dependencies dir was listed twice. Fix the reported problems in `pkg/specgen` because that was also excluded by `pkg/spec`. Enable the structcheck, typecheck, varcheck, deadcode and depguard linters. [NO TESTS NEEDED] Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
* Fix problems reported by staticcheckPaul Holzinger2021-01-12
| | | | | | | | | | | | | | `staticcheck` is a golang code analysis tool. https://staticcheck.io/ This commit fixes a lot of problems found in our code. Common problems are: - unnecessary use of fmt.Sprintf - duplicated imports with different names - unnecessary check that a key exists before a delete call There are still a lot of reported problems in the test files but I have not looked at those.

* security: honor systempaths=unconfined for ro pathsGiuseppe Scrivano2020-12-09

* Add mask and unmask option to --security-optUrvashi Mohnani2020-12-02
| | | | | | | | | Add the mask and unmask option to the --security-opt flag to allow users to specify paths to mask and unmask in the container. If unmask=ALL, this will unmask all the paths we mask by default. Signed-off-by: Urvashi Mohnani <umohnani@redhat.com>
* specgen: add support for ambient capabilitiesGiuseppe Scrivano2020-11-02
| | | | | | | | | | if the kernel supports ambient capabilities (Linux 4.3+), also set them when running with euid != 0. This is different that what Moby does, as ambient capabilities are never set. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* Stop excessive wrapping of errorsDaniel J Walsh2020-10-30
| | | | | | | | | | | | Most of the builtin golang functions like os.Stat and os.Open report errors including the file system object path. We should not wrap these errors and put the file path in a second time, causing stuttering of errors when they get presented to the user. This patch tries to cleanup a bunch of these errors.

* spec: open fuse with --device .*/fuseGiuseppe Scrivano2020-10-02
| | | | | | | | | If the container uses the /dev/fuse device, attempt to load the fuse kernel module first so that nested containers can use it. Closes: https://bugzilla.redhat.com/show_bug.cgi?id=1872240 Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* Fix up some error messagesMatthew Heon2020-08-27
| | | | | | | | | We have a lot of 'cannot stat %s' errors in our codebase. These are terrible and confusing and utterly useless without context. Add some context to a few of them so we actually know what part of the code is failing. Signed-off-by: Matthew Heon <mheon@redhat.com>

* Remove dependency on github.com/opencontainers/libpod/configsDaniel J Walsh2020-07-09
| | | | | | | | | We are using these dependencies just to get the device from path. These dependencies no longer build on Windows, so simply cloning the deviceFromPath function, we can eliminate the need for this vendoring. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* move go module to v2Valentin Rothberg2020-07-06
| | | | | | | | | | | | | | | With the advent of Podman 2.0.0 we crossed the magical barrier of go modules. While we were able to continue importing all packages inside of the project, the project could not be vendored anymore from the outside. Move the go module to new major version and change all imports to `github.com/containers/libpod/v2`. The renaming of the imports was done via `gomove` [1].
